why do we need to classify animals and plants?

Question

Hai ya, I just want to know why we need to classify animals and plants. It very important for me to know it. I hope you can't send to me your answer, please. And Thank you.

Answer 1

Just an example from the area of biological control of exotic pests...We can source pathogens, parasites, or predators that will deleteriously affect an EXOTIC pest, but before importing them, it is also necessary to test their effect on closely related NATIVE species. Say for in the example of the cane toad in Australia (Bufo marinus) - originally from tropical America, then via Hawaii - imported to predate cane beetles. The closest native relative of that beetle should have been offered to toads, and when it was seen that they habitually fed on this, depending on how necessary control of the beetle was, the next closest relative could have been offered as well, and so on. I'm not certain how rigorously this procedure was followed in the case of the cane toad, but now we have a thriving population of them in Australia that feed not only on a wide range of native organisms - not only beetles, but also other insects and invertebrates as well... So through the classification of animals, plants, and other organisms, we can know their relationships ("phylogenetic" or "hereditary" - just to throw in some new words!), and this can be used in the process of screening in biological control.

Answer 2

We need to classify animals and plants because Plants make oxegen to breath and animals help us. Like a Bee, they make honey and then we make stuff with honey.

Answer 3

How would you like to eat a poisonous plant, because you didn't know what it was ? What if a snake bite you ? It's better to what you live with.
